A net gain of 3.6 lbs. at the wheels with the new setup. Believe that I'll take that negligible increase in exchange for the absurd levels of grip and stability that I'm sensing. Seat of the pants I feel like I've gained about 25% cornering grip. I know this isn't true, but it feels so much more planted around some of my familiar roads and highway ramps. Can't wait to get out on track!
